Be it known that I, PAL E. ScHonN, a citizen of the United States, residing at Troy, count New York, ave invented certain new and useful Improvements in Button-Sewing Machines, ofwhich the following is a spec1- i'cation.

" scribed and subsequentl The invention relates to such improvementsrand consists of the novel construction and combination of parts hereinafter declaimed.

i Reference may be ha to the accompanyslmilar parts in the several fi ing drawings, and the reference-characters marked thereon which form a part of this specification. imilar characters refer to res therein.

Figure 1 of thefdrawings 1s a view 1n side elevation'of my improved button-sew` ing machine. Fig. 2 -is .a central, vertical,

longitudinal section of the work-clamp and button-holder of the same, on an enlarged l scale.v Fig. 3 is a top lan view of the same.

Fig. 4 is a, view simi ar to Fig. 2, showing a portion of the bed and work-plate with the garment inserted therebetween, and the buttonhole-stretching pin located in "the buttonhole of the garment. Fig. 5 is a simiandbuttonlar view with the work-clam ho^lder lowered, .and the wor clamped between the work-clampf'and work-plate. n

My invention relates to improvements in l machines for sewing buttons upon buttonholed garments, such as shirts and the like, the principal vobject of the invention being to -acilitate n the 'attaching ofthe button -to the buttor'i--member of the.; garment by' stitches inserted through the buttonholein the buttonhole-'member of the garment, andl through eyes orholes inthe button arranged vin line with said buttonhole.

In'carrying out my invention in its pretferredform, I employ in connection with 'an ordinaryjbutton-sewin'g machine, a butinjlocated at one side of I .the 'button-holder v1n the line of to-and-fro tombolastretching movement, "transversely of theaxis of the l' needle, of the needle, or work, as the case may-be, which pin is adapted to enter a but- '50y garment, and aiford a resistanceto the pull whereby the button-member and tonhole in the buttonhole-member ofthe exertedv uponsaid member by the o rrttor,

above the other, and the button clamped f upon the bottonhole-member be secured to the button-member, y stitches,

of Rensselaer, and State of `yieldingly force lupon the work-plate 4. y

. The worklate, work-clamp, and button` 'tion 'to inserted by the needle throu h the the 'bua-.on and thebuttonhqe into 4the bue" ton-member.

Referring to the drawin invention 1s shown in pre erred fomil1' re resents the head and, 2,: the base'o;` 1, o an ordinary button-sewing machine, of a type wherein the needle, 3, has a simple, vertical,v reciprocatory motion adapt it wherein to co erate withthe other elements o vthe stitch'- orming mechanism, not shown.

Mounted u on the bed, 2, of the machine A;

is a work-p ate, 4, whereon the work `1s adapted to rest, which plate is--mounted in slideways, 5, whereby it is guided in its reciprocating movements, transversely of the axis of the needle.

Fixed to the slide plate, 4, to move therewith,"is an overhangin arm, 6, in the head, 7, of which is mounte a vertical, reci rocatory post, 8, to the lower end of whic )is .xed a foot, 9, which serves both asa preiA .ser-foot or clamp for the work uponthe plate, 4, and as a chuck .or buttonholding the. foot being recessed at its front end at,

10 to-receive an ordinary buttomwhich is heldin position the chuck by meansjof av spring, 12, as shown in Fig. 2.

The post, 8, is adapted to means of a lever, 13, to which is connected one end of a link, 14, leading to a treadle not shown, and --ls adapted to be -oroedv downwardl of a coil-spring 15, whereby said foot is hol er. are t us,` adapted to be sirnlnltaneous y reciprocated, transversely Vofe 'axis of the needle, `3, and they may be so reciprocat'ed in any known manner, as by means be raised by" v when released from theinlu-v ence of sai actuating mechanism, by means against the work resting Y of a cam-disk 16, provided with a sinuous cam-groove, ,127, adapted `to receive a camfollower, 18on the end of a rocker-arm, 19, xed upon the rock-shaft, 20, upon which rock-shaft is also fixed-a rocker-arm, 2,1, engageable with said slidable worklate 4.

' The` cam, 16, maybe'tconnec with the main drive-shaft offy the I nachine any.'

known manner. Monntedn on-the foot 9, just inrear of the button-ho der or chuclx,

is a buttonholo engaging in, 22, fixed upon the vibratory en of a p ate-spring, 23, mounted upon said foot, said pin passing downwardly through apertures in the foot and spring, 12, so that when the foot is raised the. point of said pin projects below 'the plane of the foot and the spring, l2. When the foot is lowered, the spring, 23, permits the pin to yield upon engagement with the work-plate, 4, or the bed of the machine.

The pin, 22, is located in line with lthe eyes or holes 1n the button when properly located in the chuck or holder, it being understood that `the button is arranged with the holes through which the stitches are to be inserted in a line parallel with the direction of movement of the work.

The operation of the apparatus is as follows: The foot, 9, being raised as shown in F ig. l, and a button, 24, inserted in the chuck or button-holder, the button-member, 25, and buttonhole-member, 26, of the garment are interposed between the foot and the work-plate, 4, with the button-member resting on said work-plate. The buttonholemember is then raised until the pin, 22, enters the buttonhole, 27, therein, adapted for use in connection with the button to be attached, whereupon both the button-member and buttonhole-member of the garment are stretched longitudinally by the hands of the operator until the pin, 22, is drawn into the eXtreme rear end of the button hole-slit, after which a further pull toward the front is exerted upon the fabric by the hand of the operator, which pull is resisted by-said pin, and tends to cause the walls of the buttonhole to be drawn into straight parallel lines, whereupon the foot, 9, is depressed by releasing the treadle mechanism, and the work is thereby clamped between the foot and work-plate in the position to .which it had been stretched, in which position the buttonhole extends in a line parallel with the direction of movement of the work, and directly above the portion of the buttonmember to which the button is to be attached. While the work is preferablyprimarily placed the machine and straightened out by somewhat stretching the same by the hands of the operator, the final stretching which accomplishes the accurate locating and paralleling of the walls of the buttonhole itself, so as to form a well dened straight slit along the line of movement of the needle transversely of its-axial line, is due to the resistant coperation of the stretching.. pin. The `stitch-forming mechanism-.is then operated, the needle thereof passing downwardly through the two holes inthe button, alternately, and through the buttonhole-slit and buttonmember until the desired number of stitches have been inserted, whereu on the operation of. the stitch-forming mec anism is discontinued, thefoot, 9, raised and the garment with the button attached is drawn out of the machine, or to a position adapted for the attaching of the next button. The buttonhole being stretched longitudinally and in a line parallel with the direction of movement of the work, causes the stitches to be inserted through the slit of the buttonhole between the parallel walls of the buttonhole and not in such walls or in the fabric of the buttonhole-member.

This apparatus insures the locating of the button in proper position and dispenses with the buttoning of the arment after the button has been applied, tie garments coming from the machine with their parts buttoned together and readyfor folding and' packing. lThere is thus no disarrangement or distortion of the buttonholefdue to the buttoning operation or otherwise, so that it is possible to launder the garment before the buttons are attached and subsequently to attach the buttons, risk of breaking buttons operation.

I am aware that it has been proposed to employ in connection with a button-sewing machine, a spreading device for the buttonthus avoiding the in the laundering hole, comprising fingers adapted to forcibly separate the buttonhole walls to permit the insertion of the necessary stitches, and I make no claim to Asuch a construction. the manner of operation of my apparatus being essentially different in that the buttonhole is maintained stretched longitudinally with its walls substantially parallel instead of pulled apart laterally during the attaching of the button and to this end the buttonholestretching pin of my improved apparatus is located. in line with the button-chuck or holder in the direction of to-and-fro movement of the goods instead of at one side of, or on opposite sides of such line. i

In machines of this character, having two sets of elements, one consisting of the stitch-forming mechanismincluding a reciprocatory needle, and the other of a clamp and button-holder, it is customary to move either of said sets of elements relatively to the other, transversely of the needle, as may be desired.

I have shown and described a machine wherein the set of elements comprising the work-support, workclamp, and buttonholder are moved transversely of the needle and relatively thereto, but I do not wish to be limited to such a construction as either set of element-s may be moved as desired.

I have shown the pin, 22, slightly curved or hook-shapedbut I do not wish to be limited to such shape as any form of. pin may ybe employed, which is adapted to enter the buttonhole, and oier the necessary resistance to the stretching operation to properly locate the buttonhole-sht.

What I claim as new and desire to secure by Letters Patent is- 1. In a machine of the class described, and in combination two sets of elements, one consisting ofthestitch-,forming mechanism, including a longitudinally reciprocatory needle,- and the other of a worksu port, Work-clamp and button-holder, one o said sets being movable relatively to the other in a plane transverse tothe axial line of the needle; and a buttonhole-stretching pin at one side of the 4button-holder in line therewith in the'direction of movement 4of said relatively movable set of elements adated to engage thee-Xtremity of the buttonho e.

2. In a machine of the class described and in combination two sets of elements, one consisting of the stitch-forming mechanism, including a longitudinally reciprocatory needle, and the other of a workfsupport, Work-clamp and button-holder, one of said sets being movable relatively to the other in a plane transverse to the axial line of the needle; a spring mounted upon said workclamp and a buttonholestretching pin mounted l upon said spring and adapted,-

when the clamp is raised, to project below the plane thereof.

3. In a machine of the class described and in combination two sets of elements, one consisting of the stitch-forming mechanism, including a longitudinally reciprocatory needle, and' the other of a wo'rksupport, work-clamp and button-holder, one of said 5 sets being movable' relatively to the other in a plane transverse'tol the axial line of the needle; a spring mounted upon `said workclamp and a buttonhole-stretching pin mounted upon said Vspring and adapted, 0 when the cla-m1` is raised, to project below the plane thereof, said pin being located at one side of the button-holder in line therewith in the direction of movement of said relatively movable set of elements. f

4. In a machine ofthe class described, and

in combination, two sets of elements, one consisting of the stitch-forming. mechanism, including a longitudinally reciprocatory needle, and the Aother of a Work-support, work-clamp and button-holder, one of said sets being movable to and fro relatively to the other in a plane transverse to the axial line of the needle; and a hookshaped buttonhole-stretching pin at one side of the button-holder in line therewith in the 55 direction of movement of said relatively movable set of elements adapted to engage the extremity of the buttonhole. n

5. In a machine of the class described, and in combination, stitch-forming mechanism, including a longitudinally reciprocator needle; a work -support, work-clamp an button-holder together movable to and fro in a plane transverse to the axial line' of the needle; -and a buttonhole-stretcliing pin at one side of the button-holder in line therewith in the direction of said to-and-fro movement adapted to engage the extremity ofthe buttonhole. l

6. In a machine of the yclass described having two sets of elements, one consisting of the stitch-forming mechanism, including a longitudinally reciprocatory needle, and the other of a worksupport, work -clamp and button-holder, one of said sets being movable to and fro relatively to the other,

in a plane transverse to the axial line of the needle, a pin mounted at one side of the button-holder, in line therewith, in the direction of movement of said relatively movable set of elements, said pin being adapted to enter and engage the extremity of a buttonhole in the work be'neath the buttonholder.

In testimony whereof, I have hereunto set '85.
